Do you happen to know if LND, Core Lightning and Eclair's onchain wallets support RBF?
Discussion
Yes, all transaction done by lightning clients are RBF enabled, but can be complicated for the channels due to the multisig.

not familiar with Eclair and LDK does surely have procedures for this too.
Coming soon...
